This is an universal phone holder inspired by one I had some time ago. It is a very simple design that allows you to use different types of mobile phones and tablets both vertically and horizontally.
It has two different sized guides to accommodate different device thicknesses.
If you print sideways you don't need to use supports. Surely printing it flat would not be necessary either since the separation is quite small.

Hope you like it! Any advice, or recomendation is welcome!
